This article, which will be updated as new scripts are added, serves as an index to the scripts I have uploaded to GitHub with a quick summary of what the script can do and links to explanatory blog articles. The scripts are split logically into a number of GitHub repositories, namely:
- DailyChecks.ps1 – allows you to get a summary of your Citrix XenApp/XenDesktop 7.x deployment emailed to you via a scheduled task to help spot issues. Blog Post
- End Disconnected sessions.ps1 – finds sessions disconnected over a given duration and logs them off, optionally terminating specified processes in case they are preventing logoff.
- Get PVS boot time stats.ps1 – pull PVS target device boot times from PVS server event logs to show fastest, slowest, mean, median and mode values with the option to send an email if thresholds are breached. Blog Post
- Get PVS device info.ps1 – retrieve PVS target device information from PVS servers and display their configuration along with corresponding data from Citrix Studio, Active Directory, VMware and the devices themselves such as last boot time & IP address. Selected devices can then have operations performed on them such as deleting from PVS/AD/Studio or rebooting. Blog Post
- Ghost Hunter.ps1 – find disconnected Citrix XenApp sessions which Studio/Director say still exist but do not and mark them such that they cannot prevent affected users from launching further published applications. Blog Post
- Show PVS audit trail.ps1 – collect PVS auditing events in a given date/time range and show on-screen or export to a csv file. Can also enable auditing if it is not already enabled.
- Show Studio Access.ps1 – show all users granted access to Citrix Studio and their access levels and optionally export to a csv file. It will recursively enumerate AD groups to show each individual user with Studio access.
- StoreFront Log Levels.ps1 – display and/or change the logging levels on Citrix StoreFront servers. It can operate on multiple servers from a single script invocation. Blog Post
- Parse storefront log files.ps1 – show Citrix StoreFront log files in a sortable and filterable consolidated view, optionally filtering on entry type and date ranges. Selected lines will be placed in the clipboard to enable further research. Blog Post
- Get Citrix admin logs.ps1 – retrieve the logs viewable in Studio in a given time window and write to a csv file or display in an on screen sortable/filterable grid view. The logs can be filtered on the user who performed the action, where the action was performed from, either Studio or Director, whether it was an admin or config change action and the type of action such as logoff or shadow.
- Change CPU priorities.ps1 – dynamically change the base priorities of processes which over consume CPU so other processes get preferential access to the CPU. If a process stops over consuming then its original base priority will be restored. Can include/exclude specific users, processes and sessions.
- Trimmer.ps1 – trim the working sets of processes to make more memory available for other processes/users on a system. Can trim on demand or when processes are unlikely to need the memory such as when a session is idle, disconnected or locked. Can also set hard working set limits to cap leaky processes.

- Get installed software.ps1 – show the installed software on one or more computers where the computers are specified on the command line or via a csv file. Queries the registry rather than the win32_product WMI/CIM class which is faster and gives more complete results. Output can be to a csv file, an on screen grid view or standard output for piping into something else. If -uninstall is specified, items selected when OK is clicked in the grid view will be uninstalled. Similarly, a -remove option takes a comma separated list of package names or regular expressions and will run the uninstaller for them, silently if -silent is specified and the uninstall program is msiexec.exe.
- Group Membership Modifier.ps1 – add or remove a specified list of user accounts from local groups, such as Administrators or Remote Desktop Users, on one or more machines.
- Clone VHD.ps1 – create a new Hyper-V virtual machine from a .vhd/.vhdx file containing an existing VM, selecting the VM configuration in a GUI. Will integrate itself into Windows Explorer so you right-click on a virtual disk file and run it, elevating itself if required. Can make linked clones which can reduce disk space. Blog Post
- Fix Sysprep Appx errors.ps1 – parses sysprep logs looking for failures due to AppX packages causing sysprep to fail, removes them and runs sysprep again until successful.
- Show NTFS zone info.ps1 – Google Chrome and Internet Explorer store the URL of where downloaded files have come from in an NTFS Alternate Data Stream (ADS). This script shows these and optionally removes this information. Blog Post
- Profile Cleaner.ps1 – retrieve local profile information from one or more machines, queried from Active Directory OU, group or name, present them in an on-screen filterable/sortable grid view and delete any selected after prompting for confirmation. Options to include or exclude specific users and write the results to a csv file. Blog Post
- Show users.ps1 – Show current and historic logins including profile information, in a given time range or since boot, across a number of machines queried from Active Directory OU, group or name, write to csv file or display in an on-screen sortable/filterable grid view and logoff any selected sessions after confirmation. Works on RDS and infrastructure servers as well as XenApp. Blog Post
- Profile.ps1 – a PowerShell profile intended to be used on Server Core machines, with PowerShell set as the shell, which reports key configuration and status information during logon.
- Add firewall rules for dynamic SQL ports.ps1 – find all SQL instances and create firewall rules for them to work with dynamic ports
- Find Outlook drafts.ps1 – find emails in your Outlook drafts folder of a given age, prompt with the information with the option to open the draft. Designed to help you stop forgetting to complete and send emails. Has options to install & uninstall itself to launch at logon. Blog Post
- Outlook Leecher.ps1 – find SMTP email addresses in all your Outlook folders including calendars and write them to a csv file including context such as the subject and date of the email.
- Check Outlook recipient domains – an Outlook macro/function which will check the recipient addresses when sending an email and will warn if the email is going to more than a single external domain. Designed to help prevent accidental information leakage where someone may pick the wrong person when composing.
- Fix reminders – an Outlook macro/function which will find any non-all day Outlook meetings which have no reminder set, display the details in a popup and add a reminder for a number of minutes before the event as selected by the user. Blog Post.
- Check Skype Signed in.ps1 – uses the Lync 2013 SDK to check Skype for Business is signed in and will alert if it is not via a popup and playing an optional audio file. Can also pop up an alert if the client has been in “Do Not Disturb” in excess of a given period of time.
- Redirect Folders.ps1 – show existing folder redirections for the user running the script or set one or more folder redirections with a comma separated list of items of the form specialfolder=path. For example Music=H:\Music
- Check and start processes.ps1 – check periodically if each of a given list of processes is running and if not optionally start it, after an optional prompt is displayed. Any necessary parameters for each process can be specified after an optional semicolon character in the process name argument. Can install or uninstall itself to the per user or per machine registry run key so it runs at logon. Use it to launch and monitor key processes such as Outlook or Skype for Business (lync.exe).
- Autorun.ps1 – list, remove or add logon autoruns entries in the file system or registry for the user running the script or all users if the user has permissions. Can also operate on the RunOnce key and wow6432node on x64 systems. Uses regular expressions for matching the shortcut/registry value name and/or the command so knowing the exact names or commands is not required. Uses PowerShell’s built in confirmation mechanism before overwriting/deleting anything.
- Find and check IIS server certs.ps1– find IIS servers via OUs or AD groups or specify via regular expression, specific servers or from the contents of a text file. Check the expiry date of any certificates in use and present a list of those expiring within a specified number of days in a grid view, write to csv file or send via email.
- wcrasher.cs.ps1 – compiles embedded C# code to produce an exe file (32 or 64 bit or even Itanium) which will crash when the “OK” button of the displayed dialogue box is clicked. Use it to check that the OS is configured the desired way for handling application crashes or to produce dumps for practicing analysis.
- WTSApi.ps1 – provides the function Get-WTSSessionInformation which is a wrapper for the WTSQuerySessionInformationW function from wtsapi32.dll with the WTSSessionInfoEx class parameter. This returns an array of session information items for the one or more computers passed to it which can be used in place of running quser.exe (“query user”) and having to parse its somewhat inconsistent output.
- Trim run history.ps1 – Remove items from the history of Explorer’s Start->Run menu, and task Manager’s File->Run new task, either by specifying what to keep or what to remove via regular expression (which can be as simple as something like ‘mstsc’). Uses PowerShell’s builtin confirmation mechansim so by default will prompt before each deletion.
- Get Process Durations.ps1 – Retrieve process creation and termination events from the security event log, if auditing of these is enabled, and show the start and end times of the processes and command lines if that auditing is enabled too. Can optionally show how long after logon and/or boot processes started and can filter on specific processes and/or users. Output to csv format file, sortable/filterable grid view or the PowerShell pipeline.
- Regrecent.ps1 – find registry keys modified in a given time/date window and write the results to a csv file or in an on-screen sortable/filterable grid view. Can include and/or exclude keys by name/regular expression. Blog Post
- Leaky.ps1 – simulate a leaky process by causing the PowerShell host process for the script to consume working set memory at a rate and quantity specified on the command line.

- Sendto Checksummer.ps1 – when a shortcut to this script, by setting the shortcut target to ‘powershell.exe -file “path_to_the_script.ps1”, is added to the user’s Explorer SendTo folder, a right-click option for calculating file checksums/hashes is available. The user will be prompted for which hashing algorithm to use and then the checksums of all selected files will be calculated and shown in a grid view where selected items will be copied to the clipboard when “OK” is clicked.
- Zombie Handle Generator.ps1 – opens handles to a given list of processes and then closes them after a given time period or after keyboard input. Used to simulate handle leaks to test other software. Can open process or thread handles.
- Sendto folder size.ps1 – shows the sizes of each folder/file selected in explorer, or passed directly on the command line. For each item then selected in the grid view, it will show the largest 50 files. If any files are selected when OK is pressed in that grid view, a prompt to delete will be shown and if Yes is clicked, the files will be deleted via the recycle bin. To install for explorer right-click use and add a shortcut to this script via Powershell.exe -file in the shell:sendto folder.
- Compare files in folders.ps1 – compare file attributes and checksums between files in two specified folders, and sub folders. Files selected in the grid view when OK is clicked will then have their differences shown in separate grid views.
- Query SQLite database.ps1 – query data from a SQLite database file or show all of the table names. Queries can be qualified with a “where” clause, the columns to return specified, or it defaults to all, and the results output to a csv file or are displayed in an on-screen filterable/sortable grid view.
- Find file type.ps1 – Looks at the content of files specified to determine what the type of a file actually is. File types identifiable include various zip formats, image and video formats and executables. It will also seek out files stored in Alternate Data Streams on NTFS volumes.
